Customer Ratings & Reviews

I got this for my son for Christmas and he said this power pack was a great choice. He said it holds the charge for a long time, and tells you the percentage of the battery. I got it on sale so it is really worth it.

A bit heavy and long to charge, but what do you expect? The thing has 15,000 mAh and lasts forever unless charging more than one device, and even then it's fine. And the digital gauge is something that EVERY battery should have. Never heard of Tzumi until now, but I'll keep my eye on them.

It works great with multiple devices and the L.E.D. display is very helpful. It also stops charging things that only need a max charge. My only complaint is that they dont have 2 Qualcomm 3.0 chargers..but i love it and worth every penny!!

I love this battery for when I am on the go. I had taken it for a 2 week military thing. Well I was always outside during those two weeks. And when I needed something to recharge, this was there. It can charge several devices during the day. I highly recommend this or higher.

Great on the go charger. Comes in handy if your somewhere watching the game and there’s no wall plus around to charge your device. It charges a few phones before having to be recharged.

It works fantastic. It charges fast. I am very impressed with the product. 2 thumbs up!!!!

We are always looking for a charge on our phones, tablets, cameras, etc. this more and meets the mark. We are able to charge servers with one charge of this unit. We have two now!!

Don’t confuse this for an Anker or Aukey - brand charger. This off-brand charger seemsd to work fine, lighting up with the power button, providing an appropriate charge to watch or phone over either USB port and simultaneously. Being able to accept a charge over lighting cables was a nice touch as well. However, I had to return it because it consistently stopped charging each time between 5-10 minutes. I could get it to start again by pressing the power button, but who wants to constantly mind a charger? The only indication that it wasn’t charging would be my devices buzzing to indicate such a state. Otherwise, it wasn’t evident until the LED charge indicator went out. During one supposed charge of my phone, the phone decreased in total charge and the power pack *increased* slightly. This without external power connected so...my guess is that this device or this line has poor quality control checks on the line, poor components or both. I would definitely NOT recommend it for your travel needs.

Bought this charger to use on work trips when I didn’t always have access to regular charging stations. Works incredible and can charge my devices multiple times on one full charge

I was very pleased to find this charger at such a good price. During hurricane season, this will ease my fear of not being able to charge my phone.

Pocket sized, works with both micro-USB and lightning cables when charging.

Portable power pack battery last a very long time.

This is a great product for mobile charging; it can charge my Android multiple times on one charge. I never go home without it.

I would have bought the Anker, which I'd give 5 stars, but this charger comes in a close second.

I love this brand - I try to buy it whenever I need a new charger for myself or for a gift!

I bought another Tzumi charger and I am absolutely thrilled with both purchases. They make a quality product!

It works so great and charges phones, iPads, Apple Watch, etc super fast.

The charger works great. I like that how long it stays charged

this charger is big and a bit heavy but re-charges my phone fast and works well if you can stand to lug it around..

Good brand and very good product. definetly will buy a same product in the future
